Title: Improvements relating to frames for transparencies
IPC: G03B21/64
Filed: 1953-04-24
Abstract: 741,439. Lantern slides. JOST, J. April 24, 1953 [April 26, 1952; Oct. 15, 1952], No. 11402/53. Class 98 (2). [Also in Group XV] A frame for transparencies comprises a pair of frame members 1a, 1b, adapted to be arranged in overlying relation; each frame consisting of a glass pane on the inner side of which is stuck a sheet of material 2a, 2b comprising registering light projecting aperture 3, 4, which register when the frame is folded up, the sheet material being provided on its face surface with a adhesive, so that both frame members may be stuck together after insertion of the transparency. The sheet material is formed from a single sheet and may be provided with a marking, such as a line, a stuck-on strip or a slot, to serve as an orientation for the attachment of the transparency. The slot may be made larger than the length of the transparency so that one edge thereof may be inserted therein, and one edge of the aperture 3 may be provided with a curved projection against which the transparency may be registered and/or tilted. In that embodiment only the other three edges of the aperture 3 serve to define the image field, the fourth edge being provided by one edge of the aperture 4.

Title: Method of and apparatus for handling skins
Inventor: PITTARD CYRIL JACK
IPC: C14B1/02
Filed: 1960-03-31
Abstract: <PICT:0979151/C6-C7/1> <PICT:0979151/C6-C7/2> In a process for treating the flesh side of a hide or skin with a hair-loosening chemical, the apparatus consists of two side frames built up of metal members of suitable section, 4, 6, 8, sloping top member 10 and side brace 12. In use, the operator arranges the skin 92 on the rod 72 hair inwards, rests it on extension 86, pushes the rod forward against a paddle or blade 32 until he has moved it forward far enough to make room for the next skin (Fig. 2). When sufficient rods 72 have been inserted into the machine, so that the first rod 72 with its skin 92 will now be beneath the spray from the spray pipe 60, the indicator light 90 will be switched on automatically by means not shown, and the skin will be thoroughly wetted for ten seconds before the indicator light goes out to warn the operator that it is time for him to push the next rod 72 forward with its skin after having inserted another rod and skin, thus lowering the stop 88.  After each rod 72 leaves the spray it is carried forward steadily by the step-by-step movement of the manually operated conveyer 30 until it drops on to the continuously driven second conveyer chain 36 and by frictional contact of its end therewith is moved slowly towards the upturned end 78, the time taken to reach the head of the stack of skins on the conveyer being about twenty minutes. When the rods carrying the skins reach the upturned extensions 78, a second operative lifts each rod 72 in turn with the skin it is carrying off the rails 42, withdraws the rod from the skin and places it on the third conveyer chains 48 which carry it back to the front of the machine and deposit it in the V-shaped supports 58 ready for re-use. Figs. 3 to 6 inclusive (not shown) illustrate a modified form of machine, the general underlying principle being the same but is more fully mechanized with the conveyer chain being continuously driven and not provided with paddles or blades but reliance being placed on friction between the ends of the rods 72 and the conveyer chains 30 to progress the rods along the top member 10.  Fig. 8 (not shown) describes a machine containing one single pair of conveyer chains.

Areas of different colour are printed on the plastic coating by press 24 with an ink formed of the same liquid as the transparent plastic, having a colour agent dissolved therein, and the areas dried and cured in oven 26. The metallized web may be subsequently slit by knives 32. Similar coloured areas may be printed on the other side of the web. The areas may be constituted by overlapping bands of different colour. The printing may be effected by the rotogravure process.

Abstract: 494,264. Shot-gun cartridges. HOLLAND, J. E. D., and MANSFIELD, W. April 23, 1937, No. 11738. [Class 9 (i)] Relates to shotgun cartridges of the kind in which the pellets are retained in the case without the use of an overshot wad by turning over or crimping the front end of the case itself, the resistance to opening of the crimped mouth determining, when the cartridge is fired, the pressure available for propelling the pellets through the mouth. According to the invention, a cartridge of this kind consists of two tubes, one constituting a liner in the other and one being of metal turned over at one end to close the cartridge and the other tube stiffening or reinforcing the cartridge for handling purposes. As shown, the cartridge comprises a metal tube 1 constituting a liner in a reinforcing tube 2 from which it projects as shown at 4. The two tubes are secured to the base 3 of the cartridge. The powder 9, Fig. 6, is surmounted by a card wad 8, felt wad 7, card wad 6 and the pellets 5 which are retained in position by turning over or crimping the part 4 so as to render it more or less flush with the tube 2. According to a modification, Fig. 5 (not shown), the metal tube 1 is located outside the tube 2, extending as before beyond the end of tube 2 and being turned over to retain the pellets. The tube 2 may be of metal, a plastic material or paper.
